ANSWER:
The diagram illustrates how used paper is recycled through a four-stage process, beginning with pulp creation and ending with the production of new paper rolls.
Overall, the procedure involves mechanical and chemical treatments to transform waste paper into reusable material. The stages include making pulp, filtering, cleaning, and forming new paper, with water, chemicals, soap, and heated rollers used throughout.
In the first stage, used paper is transported along a conveyor belt and mixed with water and chemicals to create unfiltered pulp. This mixture then undergoes filtering, during which unwanted materials are removed, resulting in filtered pulp.
Next, the filtered pulp enters the cleaning stage, where it is combined with water and soap, while air is blown into the mixture to separate the remaining ink. Additional water and chemicals are added to ensure that the cleaned pulp is free of contaminants.
In the final stage, the cleaned pulp passes through heated rollers, which press out excess moisture and shape it into sheets. The finished material is then rolled up and becomes recycled paper ready for distribution. (173 words)
